Abstract: In this paper, a literature review on diagonal compression tests conducted on masonry elements reinforced by means of structural repointing technique is presented. This strengthening technique usually consists of placing in the mortar bed joints, high-tensile strength materials in the form of rods, strips, laminates or bars to increase the ductility and the overall mechanical performance of the structure. Being the reinforcing materials completely hidden after application, this system is particularly suitable for fair-faced masonry structures and historic buildings. In this paper, the main advantages and limits achieved by using reinforced repointing technique as shear strengthening system are investigated.

Keywords: composite materials; diagonal compression test; near-surface mounted reinforcement; shear behaviour; masonry wall panels; structural repointing; literature review; reinforced repointing; ductility; mechanical performance.
